Answer: 16a + 32b - 8c
Step-by-step explanation:
8(2a + 4b - c ) = 16a + 32b - 8c
Multiply 8 by 2a to get 16a
Multiply 8 by 4b to get 32b
Multiply 8 by -c or -1c to get -8c
Put them together to get 16a + 32b - 8c
Answer:
You can put it into 3 forms:
Exact form: 19/8
Decimal Form: 2.375 (Rounded=2.38)
Mixed Number Form: 2 3/8
Answer:
1) 6
2) 9
3) 80
4) 10
5) 4
6) 4
Step-by-step explanation:
1) 36 / 6 = 6
2) 45 / 5 = 9
3) 10 * 8 = 80
4) 5 * 2 = 10
5) 16 / 4 = 4
6) 12 / 3 = 4
Hope this helped!
A / B
= 80 / 8
= 10
Therefore the answer is 10
Answer:
x = 15 or x = - 
Step-by-step explanation:
Cross- multiplying gives
(14x + 6)(17x + 5) = 9x(27x + 11) ( expanding factors )
238x² + 172x + 30 = 243x² + 99x
rearrange into standard form : ax² + bx + c = 0
5x² - 73x - 30 = 0 ← in standard form
consider the factors of the product 5 × - 30 = - 150 which sum to the coefficient of the x-term (- 73 )
the factors are - 75 and + 2
Use these factors to split the middle term
5x² - 75x + 2x - 30 = 0 ( factor by grouping )
5x(x - 15) + 2(x - 15) = 0 ← take out the factor (x - 15)
(x - 15)(5x + 2) = 0
equate each factor to zero and solve for x
x - 15 = 0 ⇒ x = 15
5x + 2 = 0 ⇒ x = -
